Summary
The thyroid gland regulates metabolism and its abnormalities cause diverse symptoms. Radiological imaging, including nuclear scintigraphy and cross-sectional scans, aids in diagnosing thyroid diseases by assessing function and anatomy.
Area of Science:
- Endocrinology
- Radiology
- Medical Imaging
Background:
- The thyroid gland is essential for regulating metabolic functions.
- Thyroid dysfunction leads to a wide range of clinical symptoms.
- Understanding thyroid anatomy and physiology is crucial for diagnosis.
Purpose of the Study:
- To review the embryology, anatomy, and physiology of the thyroid gland.
- To discuss congenital, autoimmune, inflammatory, metabolic, and neoplastic thyroid diseases.
- To address the diagnostic utility of various radiological imaging modalities.
Main Methods:
- Review of scientific literature on thyroid gland function and diseases.
- Discussion of radiological imaging techniques: nuclear scintigraphy, ultrasound, CT, and MRI.
- Correlation of imaging findings with pathophysiological and morphological features of thyroid abnormalities.
Main Results:
- Radiological imaging is vital for assessing thyroid function and morphology.
- Nuclear scintigraphy offers functional insights.
- Cross-sectional imaging (ultrasound, CT, MRI) provides anatomical details and evaluates adjacent neck structures.
Conclusions:
- Comprehensive understanding of thyroid embryology, anatomy, and physiology is fundamental.
- Various imaging modalities play complementary roles in diagnosing thyroid diseases.
- Radiological assessment aids in identifying and characterizing thyroid pathologies and their impact.
